Activity - Sparkfun microSD shield switch circuit

Activity Objective

• Build switch circuit into prototyping area of the Sparkfun's microSD Shield
• Test switch circuit to ensure functionality

Activity Procedure 1

1. Review the different regions of the Sparkfun microSD shield shown below in Figure 1. Note region 1, the prototyping area.
   Figure 1: Sparkfun microSD Shield Overview
   
2. Review the switch circuit shown below in Figure 2.
   Figure 2: Switch Circuit
   
3. Review the switch circuit implemented within the prototyping area of the Sparkfun microSD shield shown below in Figure 3. Both a front and back view are provided.

4. Cut and strip both ends of two small lengths of wire (approximately $0.75in$).
5. Cut and strip both ends of one small length of wire (approximately $1.5in$).
6. Using the wires created in steps 4 and 5, a $10 k\Omega$ resistor (brown, black, orange), and an SPDT switch, construct the switch circuit in the Sparkfun microSD shield's prototyping area.
7. Solder all necessary joints.
8. Test the switch circuit by uploading the example sketch DigitalReadSerial found at File > Examples > 01.Basics > DigitalReadSerial. The serial monitor should display 0 or 1 when the switch is in the off or on position, respectively.
9. Show the Arduino IDE's serial monitor displaying the 0 or 1 values for your completed switch circuit to the instructor. The correct display of 0 or 1 will determine your quiz grade.
